Win3.x Audio Drivers Environ. Variables Win3.x Audio Drivers Environment Variables There are three environment variables used to signify information of our audio hardware : SOUND, BLASTER and MIDI. These variables will be setup by SETPNP.EXE added in the AUTOEXEC.BAT during your audio software installation. SOUND Environment variable The SOUND environment variable specifies the directory location of audio drivers and software. You can type "SET" at the DOS prompt and see the following line for the setting of the SOUND environment variable: SOUND= BLASTER Environment Variable The BLASTER environment variable specifies the base I/O address, interrupt number and DMA channel hardware configuration of the audio hardware.

Win3.x Audio Drivers
Environment Variables
There are three environment variables used to signify information of our audio hard-
ware : SOUND, BLASTER and MIDI.
These variables will be setup by
SETPNP.EXE added in the AUTOEXEC.BAT during your audio software installa-
tion.
SOUND Environment variable
The SOUND environment variable specifies the directory location of audio drivers
and software.
You can type “SET” at the DOS prompt and see the following line for
the setting of the SOUND environment variable:
SOUND=<path>
BLASTER Environment Variable
The BLASTER environment variable specifies the base I/O address, interrupt num-
ber and DMA channel hardware configuration of the audio hardware.
You can type
“SET” at the DOS prompt and see the following line for the setting of the BLASTER
environment variable:
BLASTER=A220 I5 D1 H5 P330 T6
Where:
A
Specifies the audio hardware base I/O port
I
Specifies the interrupt request line
D
Specifies the Low DMA channel
H
Specifies the High DMA channel
P
Specifies the MPU-401 base I/O port
T
Specifies the card type
